TO ALL WHGM Il MAY CONCERN:

Be it known that I, EUGENE A'rwogn, of Mansfield, in the county of Tollend, and Stute of Connecticut, have invented n new und useful Improvement in Spindles for spinningfromes,of which' the following is n. full, clear, and exact description, reference being had to the accompanying drawing, forming port of this specifica.- tion, und in Whichl Figure lrepresents e longitudinal outside viewror elevation of e spinning-freine spindle, with its vhirr constructed in accordance with my invention, und' Figure 2o. longitudinal section thereof. Y

This improvement relates to that descripticrl'of spinning-freine spindles in which the whirr is upon a sleeve that projects upwards from it, surrounds the spindle, und is connected to the latter above the bolster or top bearing, by. which lowered and outside position of the whirr, lateral strain upon the'spindle, by the tension ot' the bend upon the whirr, is prevented, generul steediness of action secured, and convenient means afforded, where desired, for theintrcduction of o. self-lubricating device to thc spindle, and its surrounding bolster, within the `whirr-sleeve.

In previous constructions of this character,thc'whirr, sleeve, und beodor cop .that connects the sleeve, end through it'the'nhirr, with the spindle, have been mode in one piece, which makes it diliienlt toget 'e true hang'of them on the spindle, though trued before' securing the some n-tl1e spindle. This my invention obviotesfond secures u true suspension or' run of the whirr h y melting the heed or cop, body or slecre, einlwhirr,l each of o seperate piece, ondirst fitting on and securing to the spindle the heed or cop, then fitting over the lower end of the cap, und uniting, by solderl or otherwise, the` upper emlof n. copper or other light tube, to form the sleeve, holding tbe same trpe, in relation tothe spindle, while performing this'operetion, by :nouns of a. rnandrel fitting over the spindle, 'and within the tube or sleeve, und afterwards uniting the whirr, by solder or otherwise, to the lower .end of tbe sleeve.

` Referring to the accompanyingdrawing, represents the spindle proper, preferably ot' n taper forni for its upper portion, ond" ot'l a. straight churn/eter for' the remainder thereof'. B is'thc'hend or oep, by which the. whirr is connected, through the sleeve, to the spindle. This cup muy be of wrought iron, end driven tight on the spindle, from its taper end to the proper peint for suspension, through the sleeve, of the u'hirr, und afterwards, if necessary, suitably secured. I then put' on the'slcere C, formed of n. seperate light tube or pi'ecc of tubing, Whichmay be cf wrought iron, copper, or other suitnble materiel, und Ht it true inrelution tothe spindle, and over the lower end of the cup, ns o downward cylindrical projection therefrom, by holding it to its place while fitting and soldering or'securing it to the cup, by or through entendi-el arranged to tit snugly over the spindle, ond within the tube, as e. filling thereto. On the lower end of the sleeve thus trued to its place, throughout its length, soy by the spindle, in the course of the slecves attachment to the head or cup, after the letter has been secured tothe spindle, I then fit ond-secure, by solder or otherwise, the whirr D. i

. ',lhis construction'insures n true hong et' thc wbirr, is lighter as o. Whole, und the device may bc got np enenp-or, considering the difficulty there is in securing u truc hung or run of the sleeve und whirr, Where mudo with the cap nll in'one piece, 'es the some is sehloni or never truc on first putting it on to the spindle, while the greatest accuracy, as regards truth, in such devices, is ubsolutely'neeessary.

What is here claimed, and desired to be secured by Letters Potent, is y The combination, with the spindle A. proper, of the hond or cop ll, tube'or sleeve C, nnd n'hirr D, mode separate 'und distinct from each otheigpnd tted and secured together for joint operation, substontolly us shown and described. 5
